Quantitative standard lyso-PG, n = 3. U1–8 represents the resonances of lipids that are at present unknown. There was no evidence for the formation of the biomarker PB in the samples used to compile this data.

Fatty acids: 24:0 lignoceric acid, 22:0 behenic acid, 18:3 α-linolenic acid, 18:2 linoleic acid, 18:1 oleic acid, 18:0 stearic acid, 16:0 palmitic acid.

aResonances for which the shifts are consistent with known lipid species (U6, DMPE; U8, PC plasmalogen) but for which no appropriate ion fragments were observed in MS.

bFatty acid profile consistent with mass given in parentheses, identified by MSn.
